V-Core 3.1 Improved Multicolor STLs

[HelgeKeck]

Not really a issue, more a suggestion.

These arms with the nice logo do scream for a multicolor print. Not everyone uses a slicer that can directly paint onto a object to create multicolor parts.

Multicolor painting on objects creates anyway very weird internal geometries

Seperate Arm and Logo parts would be much better i think. resulting in much better multicolor prints that can be used with any slicer
